Abstract (en)
[origin: EP2672715A2] 3D imaging and processing method and system including at least one 3D or depth sensor which is continuously calibrated during use are provided. In one embodiment, a calibration apparatus or object is continuously visible in the field of view of each 3D sensor. In another embodiment, such as a calibration apparatus is not needed. Continuously calibrated 3D sensors improve the accuracy and reliability of depth measurements. The calibration system and method can be used to ensure the accuracy of measurements using any of a variety of 3D sensor technologies. To reduce the cost of implementation, the invention can be used with inexpensive, consumer-grade 3D sensors to correct measurement errors and other measurement deviations from the true location and orientation of an object in 3D space.
